COOKING-STOV.

Specificationof LettersPatent No. 3,848, dated December '7, 1844.

TO all whom it may camera i Be it known that I, ADAM KETLER, of the cityof Philadelphia, in the State of Pennsylvania, have invented a newanduseful Improvement in the Manner of constructing Cooking-Stoves; andI do hereby declare that the following is a full and eXact descriptionthereof i In the accompanying drawing, Figure 1, is w a perspective viewof my stove, with the top* plate, F ig. 2, removed. F ig. 3, is a directtop view, also without the top plate. Fig. t, is a Vertical section ofthe stove, through the middle, from front to back. In each of thesefigures, where the same parts are represented they are designated by thesame letters of reference.

A, A', is the body of the stove, the part A', being the fire Chamber,which may be constructed for the burning of wood, or with a grate L, forthe burning of coal.

F, is the oven, which stands immediately in rear of the fire Chamber,and is to be covered by the to-p plate, Fig. 2. y

B, is a partition plate which divides the fiue space between thetopplate of the stove and the oven, into two unequal compartments, P,and Q; the former being four, Or five, times the size of the latter. Theplate B, may be made to fall down when a direct draft is to be made tothe exit pipe; or it may -be furnished with a sliding damper, admittinga passage a through it for that purpose. i

H, is a fiue space between the back plate of the fire Chamber and thefore plate of the oven; H', a like space under it, and H", one in therear thereof. The top of the oven has a double plate extending over thecompartment, P, having a heated air space, a, a, between the two plates;there is not any draft through this space, but it serves to prevent thetop plate of the oven from being too *intensely heated. This space, asabove noticed, extends Only over the compartment,

P, the top plate of the oven, at Q being single, as the heated air willhave passed D, of said compartment.

under theoven before it arrives at this compartment. r

G, is the fiue space through which the draft ascends into thecompartment Q, on its way to the exit pipe, I, at the rear end The fiuespace, H", at the back of the oven extends from side to side of thestove, but it is inclosed at top in the rear of the compartment Q by the'continuance of the top oven plate Over it, as at Q'. The fiue space G,leads up from the fore and bottom fiue spaces H, and H'.

In using this stove, the heated air from ,the fire Chamber passes upthrough the opening J, in the ordinary manner, into the compartment Q,above the upper double oven plate, then down the rear fiue H", under theoven through H', and up through the opening G, into the compartment Qand along this to the exit pipe in the rear.

Having thus, fully described the manner in which I construct my cookingstove, what I claim therein as new, and desire to secure by LettersPatent, is

The particular combination and arrangement of parts-by which the actionand pas- Sage of the heated air from the fire chamber to the exit pipe,are governed as herein v described; such combination and arrangementconsisting in the dividing of the upper horizontal fiue, above the oven,into two unequal parts, P, and Q; the part P, covering the large portionof the oven; in this part, being furnished with a double plate, thedirect passage from the fire Chamber being over it, and the compartmentQ, being separated from the oven by a single plate, and admitting theheated air into it through a fiue opening G, at its fore end, and alongit to the exit pipe I, at its rear end; the whole combination beingsubstantially the same with that herein set forth.

ADAM KETLER.
